Allocating many object

To see the difference to Java...
public class Alloc {
int[] val;
public Alloc()
{
val = new int[10];
}
public static void main(String[] args) {
Alloc[] arr = new Alloc[1000000];
for( int j = 0; j < 1000; j++ )
{
for( int i = 0; i < 1000; i++ )
{
arr[j*1000+i] = new Alloc();
}
System.out.println( "loop "+j );
}
System.out.println( "complete " );
}
}
Note, this Java program make a second allocation for the array and does
also initialize the memory.
The program was finished after ONE second.
This 1000 times faster like the D program.
So I have to say that again... The GC is a show stopper and need to be
changed.
